How do I correct business credits that somehow appeared in Home and Business

You will need to go back through your entries to see if you see anything that is incorrect.  To go back to the Home office expense section:

1. Open or continue your return.
2. Search for Schedule C and select the Jump to link in the search results.
3. Answer any questions about your business until you get to the Your self-employed work summary screen. Select Edit or Review next to your business.
4. You'll be asked to select the expenses you know you had.
5. Select Home office. You can also select any other expense categories that apply to your business. 
6. Select Continue at the bottom of the screen when you're done.
7. On the Here's your [type of work] info screen, scroll down to the Expenses section, and select Start next to Home office.
8. Enter the info about your home office.  

Feel free to reach back if after reviewing you entries your issue continues.
